This amounts to a de facto ban on community organized air-quality monitoring. “In enacting CAMRA, the Louisiana legislature targeted community air monitoring for unique and onerous restrictions,” the lawsuit reads. In many cases, low-cost air monitors are the best tools for this job. To stop community air monitoring, lawmakers are relying on a categorically false idea: that air quality can only be measured by bulky, expensive, and professionally operated air monitors. A decade ago, before the advent of low-cost air quality monitors and the development of sophisticated analytical tools, pricey air quality monitors were one of the only tools available for air-quality measurement, mapping, and prediction.
